在`MyDate`类中,如果我们按照您的描述,它应该是一个代表日期的对象,包含了年份(year)、月份(month)和日期(day)三个基本属性。下面是一个简单的`MyDate`类的示例:
```java
public class MyDate {
private int year;
private int month;
private int day;
// 构造函数
public MyDate(int year, int month, int day) {
if (year < 0 || month < 1 || month > 12 || day < 1) {
throw new IllegalArgumentException("Invalid date");
}
this.year = year;
this.month = month;
this.day = day;
}
// Getter methods for the properties
public int getYear() {
return year;
}
public int getMonth() {
return month;
}
public int getDay() {
return day;
}
// Setter methods to modify the properties
public void setYear(int year) {
this.year = year;
}
public void setMonth(int month) {
this.month = month;
}
public void setDay(int day) {
this.day = day;
}
// Overriden equals(), hashCode() and toString() methods for better object handling
@Override
public boolean equals(Object obj) {
if (this == obj) return true;
if (obj == null || getClass() != obj.getClass()) return false;
MyDate other = (MyDate) obj;
return year == other.year && month == other.month && day == other.day;
}
@Override
public int hashCode() {
return Objects.hash(year, month, day);
}
@Override
public String toString() {
return String.format("%d-%02d-%02d", year, month, day);
}
}
```
在这个类中,我们设置了构造函数来验证输入的日期是否有效,并提供了getter和setter方法来操作各个属性。同时,还覆盖了`equals()`、`hashCode()`和`toString()`方法,以支持日期比较和其他常见操作。
